Hello everyone:          Nowadays different feed companies originated and different feeds available at different prices. All companies said that, our feed is good for inatake and survival and gives good results like this... But farmers got confused for the selection of feed.  What farmers do?          Usually some farmers get connect with each other. If one farmer tell that , this feed is good for culture, you can try this. Then automatically other farmer also bought this.. like this happening on many places. Where the confusion starts?         Many graduates are doing farming. Those graduates select by protein percent in the feed. The graduated farmers thinks that, all companies vannamei feed have same protein percent, same lipid percent but how the growth varies from company to company....         All are knows that, all companies formulated the feed as per the nutritional requirements of vannamei. How the good quality feed produced ?        It is fully depends on the fe

Hello everyone:          Today we will see the effects of Bleaching in shrimp pond. In shrimp farming, we use different source of water like bore, creek, well, sea water. Whatever it is, we will go for bleaching as a disinfectant. Based on the source , the percentage of Bleaching varies. What the bleaching powder contains?            It contains chlorine, it is an active reactive compound for disinfectant. Most of the bleaching powder have different percent of chlorine. Based on that we can calculate and go for bleaching. Which time can I go for bleaching?           If you have an treatment tanks means, you can go for bleaching on that tank. After Bleach you can pump water to growout. Bleaching can actively oxidizes the organic matter, it kills pathogens,  Sometimes pests, it kills planktons.. so it is better to go for Bleaching before fertilization. How it kills microorganisms?           Chlorine compound have more electrons. So these electrons can easily replace the hydr

Hello everyone:          We will see some of important strategies for feeding. Feeding based on body weight.        It is better to go for feeding based on the average body weight of your shrimp. If your shrimp have 10 gram weight and you go for 3% of the body weight which means 0.35 gram you have to give to your shrimp. First observe the average daily growth and weight by sampling. By this you fix the day feed by the biomass and go for feeding with the help of check tray.  My suggestion:         If you are culturing with high stocking density means, the feed and wastes are always high . So properly use the aerators for sludge accumulation at the centre. Properly use probiotics to your pond. It is better to avoid feeding at centre of the pond.       If you feed to the centre of the pond means, the animal will disturbs the sludge at the time of taking feed. It leads to release of toxic gas like hydrogen sulfide.         It is better to maintain the dissolved oxygen level at more than 3.

Hello everyone:           Today we will continue some important functions of biofilm in pond. # In some researches told, the useful nitrifying bacteria and heterotrophic bacteria are present in the biofilm. They effectively involves in the purification of water. The heterotrophic bacteria present in the biofilm also forms microbial proteins with highly nutritious. # All essential nutrients like protein, lipid , vitamins are present in the organism which is present in the biofilm # Another intresting facts by research is......          The nitrifying bacteria present in the substratum ( biofilm) is doing good nitrification process compares to the bacteria suspended in the water.. It is a very intresting facts. # Turbidity causes various problems in shrimp pond. I already mentioned in one of my post about molting. In molting time, shrimp doing some things like hiding and also creates Turbidity. So depth maintenance is important. This biofilm also reduces Turbidity in your pond water.   #

Hello everyone:          Today we will see some interesting topic about biofilm formation and uses in shrimp culture...          In Aquaculture, we using different artificial pellet feeds.. only very few of people are culturing with natural productivity.. we always stock in high stocking density. Minimum duration of time, we have to harvest. So we give more feeds and leads to change in water quality. Biofilm function in shrimp pond..         Before stocking, all are applying fermented juice. I already clearly posted about this. At that time we continually runs the aerator.. we do chain dragging for proper mixing of nutrients and also make the soil strengthen.          Biofilm consists of different organism like microalgae, different beneficial bacterial colonies, protozoans... These all are very rich in nutrients. They have growth promoting substances, many bioactive compounds, antibiotics compounds... These all are present in the biofilm.           Many researches told, there is an in

Hello everyone:            Today we will see the important criteria should be followed for better farming activity..... If you have shrimp farm, then you must follow these things... Remember : We are not cultivating fishes, we are cultivating shrimp, comparing to fishes, shrimp can't have such better immune system. So the maintenance must be neat.... 1. Importance of nursery maintenance in shrimp farm. 2. Tips for farming shrimp with direct stocking. 3. Seed selection with good quality. 4. How to overcome size variation in shrimp pond. 5. What are the things you have to do for better feed management. 6. How to increase feed intake for shrimp. 7. Good biosecurity. 8. Water quality management. 9. Importance of sampling at regular intervals. 10. What are the things, the feed boys must know. ..........        If you got any failure crop, don't worry.... First relax and analyse the all the things happened throughout the culture.... Write step by step.. point the mistake... Next time

Hello everyone:          Everyone heard about Running mortality syndrome in vannamei farming . Use of chemicals, under high stocking density, improper environment management leads to occurance of new disease in shrimp farming.  Difference between syndrome and disease:           All are confusing, why we tell syndrome and tell disease.      Disease - from known pathogen. We can tell this disease is caused by this pathogen.     Syndrome - we tell syndrome, when we don't know the proper causative agent for the infection. You can see occurance of group of symptoms.  Running mortality syndrome:       It is also one type of syndrome. Till we can't tell the proper reason for occurance of this syndrome. After stocking of shrimp, it dies daily from 30 or 40 th DOC. Daily death occurs and leads to very poor survival at the end of the culture . It leads to early harvest of the culture.       From the histopathological analysis of various studies told , there is a presence of high B cell

Hello shrimp farmers:           First I would like to thank to the farmers who contacting me. I hope my answers definitely helps them for better farming activity...           I thank to people who visited and share my blogs. I am happy to share, my blog reached more than 6 thousand viewers from 40 different countries... Questions are always welcome.....             Many Farmers are asked many doubts regarding varies topics... Another interesting thing is, now farmers are very interested for learning about shrimp farming..             I request to the people, pls make an comment of your, 1. Doubts regarding shrimp farming. 2. Major problems faced during the culture. 3. I will tell Max from my knowledge. You can post by comment or send me an Email. I will clarify your doubts at extent from my knowledge. Pls follow and share by blog page.  Pls comment or mail your questions. * Mention the important problem you are faced during the culture.                                         Thank you
